My hometown is Nanjing.Nanjing,with a long history,is located in the area of the Yangtze River’s downstream.Nanjing used to be the capital of China in the Wu,Dongjin dynasties and the Song,Qi,Liang,Chen of Southern dynasties.So Capital of six dynasties is another name for Nanjing.Not only in these six dynasties,at the beginning of Ming dynasty and the Republic of China,Nanjing was also the capital of China.It won’t be amazing that there are lots of buildings which were built in different dynasties in Nanjing.Confucius Temple,Presidential Palace and Dr.Sun Yat-sen's Mausoleum are the most famous and attractive sites in Nanjing .
